im a bit pissed cause i went to my local bike shop and told the mechanic i was worried about the tension on my wheel..he was like "uhmmm i have to much work, maybe friday ill look at it, but don't worry nothing will happen to the spokes" and now this...GRRR

Check my answer in the mechanics section but I pretty sure you have 16" or 349 sized wheels. At least my bike does. Roger

yes, thanx man!

i just came back from Bike Stop they told me i could ride tommorow but i needed to bring them in asap to prevent more broken spokes. He said "if i dont have the spoke size ill make one for you, dont worry so much man, if you were to respoke the entire wheel then we would need to buy new spokes, but for one! ill do it!"

If it was my Moulton I would be re-spoking both wheels with new stainless steel spokes...for a few reasons.
As this is an unrestored bike and you may not know if these are the original spokes and as a spoke has broken already it can mean the rest are starting to fatigue so by replacing only one you may find another then another will break not too far down the track....it's good to know what you're dealing with.
Also, the quality of the factory spokes are probably low-end so upgrading to SS would be a good idea as they are much stronger. The SS spokes are not cheap, here in Australia they are $3 ea, but they're worth it. If my LBS doesn't have the right length they will cut to size rather than order in special sizes ie: 24" to 451.
